Introduction of BIOS
3-25
ä
PCI-slotX: Some old PCI IDE cards cannot be detected by the BIOS. If
the onboard BIOS cannot detect a PCE IDE card, you have to specify
on which PCI slot the IDE card is inserted, to make the BIOS assign
IRQ14 for use by the interrupt number (INT#) of this PCI slot.
ä
ISA: If you select ISA, it means that your PCI IDE card features a
“
paddleboard
”
and a cable that can be connected to IRQ on the ISA slot,
because the BIOS will not assign any IRQ to this PCI slot.
Attention:Primary Channel and Secondary Channel : The BIOS needs two
independent interrupt number (INT#) lines to be allocated to the
PCI IDE card. Be careful not to choose twice the same interrupt
number (INT#).
Note:
Since the interrupt number of the PCI slot is connected according
the design described below, there are some limitations, be careful.
+
The INT#A signal of the first PCI slot, the INT#B signal of the
second PCI slot, the INT#C signal of the third PCI slot and the
INT#D signal of the fourth PCI slot, are the same, so be careful
not to use them simultaneously.
+
The INT#B signal of the first PCI slot, the INT#C signal of the
second PCI slot, the INT#D signal of the third PCI slot and the
INT#A signal of the fourth PCI slot, are the same, so be careful
not to use them simultaneously.

On Board USB Controller:
This is to Enable or Disable the onboard Universal Serial Bus (USB)
controller.
Onboard PS/2 Mouse:
This is to Enable or Disable the PS/2 Mouse. When in Enable, IRQ 12 is
used.
